This lesson examines the many warnings God gives throughout Scripture concerning spiritual danger, deception, and falling away from the faith. Jesus and the apostles repeatedly command believers to “beware” — of false prophets, corrupt doctrine, hypocrisy, covetousness, false teachers, worldly philosophy, vain deceit, and spiritual backsliding. These warnings were written to protect Christians from being led away from the truth and from developing hearts that drift from God. In this study, we will carefully consider these biblical cautions and learn the importance of discernment, steadfastness, humility, and remaining faithful to Christ and His Word.
